To all whom t may concern:

Be it known that I, GEORGE RoEssLER, a citizen Of the United State-s, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Multiple Reproducing-Machinc; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the aecompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to means for reproducing forms from a mold. It has to do with a means for forming shapes, 1n imitan tion of patterns. It also has for its object to provide a machine that will automatically produce from patterns, contours of surface like that of the pattern. It particularly has for its object to produce metal molds in multiple of the same or different sizes in imitation of the shape of the surface of a pattern.

Constructions containing the invention may partake of different forms. I have selected one of such constructions as au eX- aniple and the same is described hereinafter and illustra-ted in the drawings.

Figure 1 of the drawingsvis a top view of the construction selected, Fig. 2 is a side view of the construction, and Fig. 3 is an end view of the construction. Fig. 4 is a side view of the pattern shown partly in section to illustrate more clearly some details of construction. Figs. 5 and 6 illustrate sectional views showing end and side views of gear wheel connections of parts of the mechanism. The sections are taken on the broken line 5 6 indicated in Fig. l. Fig. 7 lis a view of the telescoping shaft used for driving the guiding pointer that moves over the pattern. Fig. 8 is a view of the worm gearing for moving the pattern. Fig. 9 illustrates the cutting end of the cutters and Fig. 10 illustrates the pointer used in the machine set for the particular ratio of sizes that is shown in the illustration.

1 is the supporting base or bed of the machine having` at one end arms or brackets 2 in which is pivoted a shaft 3 to which is connected the guiding and cutting tools of the machine.

The guiding' tool 4 is secured by means of a suitable chuck to a shaft or spindle supported in bearings located in the housing 5 that is connected to the arm 6. The arm 6 is connected to the shaft 3 and consequently rotates the shaft 3 in the bearings formed in the ends of the brackets or arms 2. The housing 5 is supported on a bifurcated arm 7 forming an extension of the arm 6. A part of the housing 5 extends through the furcations and is clamped in position by means of a. plate 8 and bolts 9 that securesl thehousing 5 in the position in which it may be adjusted along the extension arm 7. A gear wheel lO is connected to the pointer 4 for rotation of the pointer. T he rotation of the pointer permits it to readily slip along the surface of the pattern and prevents any binding that may occur by reason of the movement of the pointer 4 relative to the patv tern, it being held in constant contact with the pattern by the weight of the arms connected to the shaft 3 and the weight of the parts for causing rotation of the pointer and the tools. The gear wheel 10 is preferably a beveled gear wheel and meshes with the beveled gear wheel 11 that is connected to the telescoping shaft 12, the parts of the shaft 12 being slipkeyed together by the key 13 shown in Fig. 7. rFhe outer end of the shaft 12 is support ed in a bracket 14 that is secured to the housing 5. vIt is also supported in brackets 15 and 16 located on the arm 6. The shaft 12 is driven preferably by an electric motor 17 through gear wheels 18. The motor 17 is supported on a bracket 19 that is secured to the arm 6 and to a certain extent its weight countcrbalances the weight of the mechanism secured to the shaft 3.

The cutting tools that reproduce the contour of the pattern to be imitated are supw ported on arms 2O that are keyed to the shaft 3. The arms 20 move with the arm 6 and consequently the cutting tools may be driven from the shaft 12 that is supported in bearings located on the arms 6. The shaft 12 is provided with a beveled gear wheel 21 that meshes with the bevel gear wheel 22 that is keyed to the shaft 23. Bevel gear wheels 24 are also connected to the shaft 23 and operate on bevel gear wheels 25 supported in bearings located and extending transversely through the arms 20. The gear wheels 24 may be located intermediate bracket arms 26 formed on the arms 20 and the bevel gear wheels 25. Cutting tools 27 are connected to the gear wheels 25 and are rotated thereby.

rlhe pointer 4 and the cutting tools 27 are located so that the axes of'their rotation is substantially at right angles to the surfaces pf the pattern and molds respectively and thus permits the tools to ride over the surfaces of the pattern and molds in the to and fro movement of the pattern and molds. The nose of the pointer is rounded as is also the end of the cutter. The sizes of the tools are'made smaller tliairtlie smallest curvature of any part of the surface of the pattern inv the one case, and the mold in the other case. Furthermore, the ratio of the sizes of the noses of the pointer and the cutters is the same that of the distances of the pointer and cutters from the axis of the shaft 3 on which .they are support-ed in order that there may be a true reproduction of the pattern by the cutting action of the cutters, that is, in order that the cutters .may follow the varying lilies of increments of the pointer in reproducing in the molds the contour of the pattern. Moreover, the lengths of the shanks of the pointer and the cutters may also have the same ratio that exists between the lengths of the arms supporting the pointer and supporting` the cutters, in order that the points of contact of the tools may be located at distances from the axis of rotation of the pattern and molds suilicient to insure room for operation of the cuttingtools on the side edges ofthe molds. In the particular form of construction shown in the drawings, the patterns are substantially semifcylindrical and substantially semi-cylindrical molds are cut from rough castings by the operation of the cutting tools, the machine being particularlyY designed for forming molds for glass bottles. The axes of the pattern aud the molds are located parallel to the axes of'rotation of the pattern and molds in order that the pointer which is supported by the telescoping arm 6 and the cutting` tools supported by the arms 2O may follow and eut to the very edge of the semi-cylindrical surface. Also in the preferred form of the construction illustrated, the pattern is made very much larger than the molds, which reproduces with greater accuracy the form of the pattern in the molds, the ratio of the dimensions of the pattern to the molds being the same as the ratio between the length of the arm that supports the pointer to the length of the arms that support the cutting tools. Also the-distances from corresponding parts of the pattern and the molds from the axes of rotation of the pattern and molds bears the same ratio. The tools thus operate upon the pattern and molds at points that are re mote proportionate distances from the axes of rotation of the pattern and molds. The revolving pointer and cutters operating on the pattern and molds thus located remote from the axis of rotation of the pattern and molds holds the tools practically perpendicular to the inner face of the pattern and molds at all times and readily permits the pointer to move over the patterns and prevents the arms from springing sidewise when working on acute angles. lt also permits the use of exceedingly large cutters for cuttingy the surfaces of the molds.

The pattern 28 may be formed of any material such as sheet metal. It is laid in a bed 29 that is supported in a carriage 30 having standards in which the bed 29 is pivotally supported.A The bed 29 is connected to a worm gear wheel 40 that is rotated by the worm 3l from time to time and previous to the beginning of the cutting operation of the cutters 27 which take place during forward movements of the pattern and molds. The worm 3l is located on a shaft 32 to which isl also connected a spiral gear 33. The spiral gear 33 is operated by the spiral gear 34. The spiral gear 34 is slip-keyed on a shaft 35. The shaft 35 is rotated by the spiral gear 36 and the spiral gear 37 with which it meshes. A cog or ratchet wheel 38 Ais connected to the spiral gear 37. The ratchetV wheel 38 is operated by a dog 39 that is pivoted to the carriage 30 by the pivot pin 41. l/Vhen the carriage 30 moves so as to carry the pointer 4 to the forward end of the pattern andthe cutters 27 to the forward ends of the molds, the dog 39 moves the wheel 38 one or two steps accordinpto the position that the dog 39 may be adjusted onV the carriage 30,

The dog 39 is secured to a block 42 that mayl be adjusted in any desired position along the carriage 30 by means of a bolt 43.

Rotative movements of the bed 29 are reproduced in the molds 44 but in a ratio that is the same as that-existing between theV arms 6 and 2O that carry the pointer and the cutters. Inasmuch as the points of operation of the cutters are located from the axes of the rotation of the molds and the pointer is locatedfrom the. axis of the pattern, distances that have the same ratio as the distances of the tools from the axis of the supporting shaft 3, the molds are rotated angularly the same as that of the patterns. Consequently the molds 44 may be rotated by the operations of the shaft 35 which is rotated step by step by the dog 39 operating upon the wheel 38. The shaft- 35 is connected through spiral gears 45, 46, shaft 47 and worms located on the shaft 4T to the worm Wheels 43. rl`he shaft 47 is supported in the carriage- 49 while the gear 45 is slip-keyed to the shaft 35 so that as the carriage 49- to which the molds 44 are connected moves to and fro on the bed l, thegear 45 slips along a shaft The gears 45 and 34 are located inarms 50 formed on brackets 5l connected te the carriage 39 that supports the pattern and the carriage 49 that. supports the molds whereby the gears 34 and 45 are kept in mesh with the gears 33 and 46 which are connected to shafts supported in the brackets 51 and are caused to move to and fro with the carriage. The molds are connected with the worm wheels 48 by means of shafts that extend through housings 52 formed on the carriage 49. They are connected to the shafts by depending arms 53 having a suitable face plate 54. The arms 53 locate the molds a short distance below the axes of the shafts passing through the housings 52. This distance is such that the finished surfaces of the molds bears the same ratio to the distance of corresponding parts of the surface of the pattern from its axis of rotation. as the distances of the cutting tools from the shaft 3 bears to the distance of the pointer from the shaft 3.

The pattern is supported in the bed 29 and the molds 44 are so located on the plates 54 that the distance of the surface of the pattern from the axis of rotation of its supporting bed 29 has the same ratio to the distance of the finished mold surface from the axis of rotation of the mold that the distance of the adjusted position of the pointer from the shaft 3 has to the length of the arms 20. Thus different sized molds may be produced from the saine pattern, or the same sized molds may be produced from different sized patterns, the ratio of the distances of the tools from the shafts 3 being kept the same as the ratio of the distances of the operative ends of the tools from the axis of rotation of the pattern in the one case and the finished surface of the mold in the other case.

The feed of the carriages 30 and 49 must also bear the ratio characteristic of the Inachine, namely, the ratio of the distan-ce of the pointer from the shaft 3 to the distance of the cutting tools from the shaft 3. The feed of the carriage 30 is produced by the motor 56 suspended on the bed l which operates through gear wheels 57, 58 and 59. The gear wheel 59 is keyed to the shaft 60 which is provided with the screw 61 that passes through a depending portion 62 of the bed 30. Rotation of the shaft 60 causes back and forth movement of the bed 30. A different rate of movement is transmitted to the carriage 49 from the motor 56 through gear wheels 58, 63, 64, 65, 66, 67, shaft 68, gear wheels 69, 70, and shaft 7l on which is also located a screw that passes through a part on the carriage 49 to operate the carriage 49 in the same manner as the carriage 30 is operated.

In order to obtain the desired rate of movement of the carriage 49 to the movement of the carriage 30, the gear wheel 63 may be readily removed and an idler 64 of the desired size may be placed intermediate the gear wheels 63 and 65 or the gear wheel 64 may be placed on a movable arm 72 that may be readily swung from between the gear wheels 63 and 64 and replaced when the desired gear wheel 63 has been connected with the gear wheel 58.

The reverse movement-s of the carriages 30 and 49 may be obtained by reversing the current through the motor 56. A pin 73 may be secured to the carriage 30 and a rod 74 may be supported in brackets 75 that are secured to the bed l. The rod 74 may be moved along the bed l by the pin 73 operating on the adjustable fingers 76 that are secured to the rod 74. The rod 74 may be connected to an arm 77 and operates a suitable reversing or a three point switch 78 when the pin 73 moves the rod 74. A rheostat 79 may also be connected into the circuit for varying the speed of the motor 56 when the molds are being returned in the manner well known in the art. When the pin 73 strikes one of the fingers 76, it causes movement of the bed 30 away from the shaft 3 and when the pin 73 strikes the other finger 76, it causes movement of the bed 30 toward the shaft 3. Inasmuch as the carriage 49 is moved by the motor 56, the movements of the bed 30` are reproduced in the bed 49 except that the bed will move distances which bears a ratio to the distance that the bed 30 moves that is the same as the ratio of the machine. l/Vhen the bed 30 returns and just before it strikes the finger 76 nearest the shaft 3, the dog 39 operates on the wheel 38 to cause a short angular rotation of the bed 29 that supports the pattern 28 and the plates 54 that support the molds 44 so that upon the return movement of the carriages 30 and 49, the pointer 4 will ride over the same corresponding line on the surface of "the pattern that is being cut and finished by the cutters 27 operating on the molds 44. The machine thus continues in its feeding operations until the surface of the pattern has been passed over and the surfaces of the molds have been completed.

The cutting tool is provided with a round cutting nose 80, while the pointer tool is provided with a semi-spherical end 81. The noses of the tools bear the same ratio of the machine, that is, the ratio of the distances of the tools from the shaft to which they are connected. The rotation of the cutting tool 27 will describe a semi-spherical surface that will have a radius that bears to the radius of the semi-spherical end of the pointer tool 4 a ratio that is like that of the distances of the tools from the supporting shaft 3. By this means the cutting tools 27 will cut and form finished surfaces exactly like that that the spherical surface of the end 8l of the pointer 4 passes over.
